I'm curious about the turbo style tensioner? Spring type? Have a part number handy?

Thanks,

These Pelican Parts - Product Information: 930-105-053-00-M260 the last of the contained oil / spring type, some call them "turbo" because of the 930 part no.

Did you ever figure out the problem?

I did. turns out all the head studs on the right side were lose. It's a head scratcher as to why but every head bolton the right was lose a 1/4 turn.

Torqued them all back up and runs like a champ again.

Switching to the tensioners back to the "Turbo" type got rid of the "noise". I don't know if it was really a problem in the first place, or if the pressure fed tensioner's were bad or the different chains were just noisy. I suspect the pressure fed tensioner's apply more tension to the chains than the Turbo type. I do get a little chain noise at cold start up for about 30 seconds until the tensioner's even out, had that same issue with the pressure fed type before the rebuild.
